I just found out my 5 yr old is a 4 on the skin test for a peanut allergy. Is a blood test or a skin test better?

I am new to this, and certainly no expert, but my ped said that the skin test is more accurate.

We went to Dr. Wood @ Johns Hopkins - a respected expert on food allergies. He uses the blood work and recommends NOT using the roman numeral categories but using the raw scores (1-100) from the blood test

I heard that a skin test is generally more sensitive, and that any positive (i.e. certain mm larger than the control) is a positive, no matter how large the wheal. Our allergist doesn't give a "class" sensitivity.

Thank you. I will get him some bloodwork as well.

Both, with reaction history, and family history. sarah

My 6 year PA DS has never had a skin test...the reason....he has had reactions and bloodwork....Class 6...skin test is too dangerous for him.

I think the testing methods vary...one is not necessarily better than the other. It depends on the individual situation.

I am curious why a skin test would be so risky?

I was told that since my son is contact sensitive, Class 6, and has had anaphylaxis reactions that the test itself could cause a serious reaction....and is totally unnecessary for him.

Since the skin prick test introduces a tiny amount of allergen into the skin this testing is not appropriate for my DS.

Thanks for explaining that to me ...my daughter's reaction to the skin test was severe....and after it was over i wondered if i did the right thing...then we did the blood test and it was 93 ...not sure what class...
